Title: Strain gage assembly for measuring excessive tensile strain of a flexible elongated member, such as a steel structural cable, or an electrical transmission cable, or a glass fiberoptic communication cable, which may slightly twist under tensile strain
Inventor: TIJMANN WILLEM B
IPC: G01L1/10
Filed: 1991-04-10
Abstract: A strain gage assembly is secured between two initially longitudinal locations on the exterior of a flexible elongated member, such as a steel structural cable, or an electrical transmission cable, or a glass fiber optic communication cable, after or before the installation of the flexible elongated member, to thereafter upon the subsequent pre-stressing and/or the possible excessive straining of the cable, create an observable or transmittable reading of the excess tensile strain being sustained by the flexible elongated member. This strain gage assembly includes, in one embodiment, the in line arrangement of a vibrating wire strain gage, having the vibrating wire thereof secured to a calibrated coiled spring, which in turn is secured to an inner tube shaft, which in turn is telescopingly fitted within an outer tube shaft, that is secured to the vibrating wire strain gage. By using two spaced securement means, such as clamps, this strain gage assembly is secured to the exterior of a flexible elongated member. One securement means secures the combined vibrating wire strain gage and the outer tube shaft to the flexible elongated member at one location. The other securement means secures the combined calibrated coiled spring and the inner tube shaft to the flexible elongated member at a spaced second location. The inner tube slightly radially turns relative to the outer tube, within controlled limits, to compensate, if necessary, for any slight twisting of the flexible elongated member, which may occur when the flexible elongated member is excessively strained in tension.      This strain gage assembly, when installed, may also include a thermistor to signal temperature changes, a data transmission means via electrical cable leads of electrical circuits, and/or a signal transmitter means via radio waves, optionally utilizing satellite transmissions or meteor burst transmissions, and/or a protective cover, and/or a vibrating wire readout instrument.      When the flexible elongated member is a tieback steel structural cable, for example, the strain gage assembly created reading may be read at random times, at scheduled times, or constantly, during either static or dynamic loading periods of time.      Observations may be made before, during, and after earthquakes.

Title: Remote control system for central vacuum cleaners
Inventor: MAHER EUGENE J JR
IPC: A47L9/28
Filed: 1991-08-27
Abstract: REMOTE CONTROL SYSTEM FOR CENTRAL VACUUM CLEANERS    Abstract of the Disclosure A remote control system for actuating a central vacuum system from a remote location such as a vacuum cleaning hose handle without the use of a separate, dedicated system of control wires.          In a preferred embodiment, a small, lightweight FM radio frequency signal transmitter is installed in the hose handle and the signal is conducted along the household current 60 Hz wires running through the vacuum cleaner hose and wand for the purpose of providing electrical current to power sweeper brush motors.  The piggy-backed control signal requires no additional conductor wires, such as the low voltage wiring of conventional control systems, thereby saving weight and costs.  The control signal travels along the power supply wires running the length of the vacuum hose, which are preferably covered by a sleeve, such as of cloth or plastic, then through a standard plug into a standard electrical outlet.  A receiver located near the central vacuum cleaner system receives the control signal from the house wiring and processes it to start or stop the central vacuum system main motor.

Abstract: Use of a sorbent for continued removal of nitrogen oxides and sulfur oxides from a gas containing them and for the regeneration of the sorbent. The sorbent is made by incorporating an alumina stabilizing agent into the sorbent. A preferred method is to add the stabilizer when the alumina is precipitated. The precipitated powder is formed subsequently into a slurry, milled and dripped to form the stabilized spheroidal alumina particles. These particles are impregnated with an alkali metal or alkaline earth metal to form the stabilized sorbent. Alumina stabilizers include one or more of silica, lanthana, other rare earths, titania, zirconia and alkaline earths. <IMAGE>

Abstract: Les voilures existantes sont en général le plus allongées possible afin de permettre un meilleur rendement telles que les lois de l'aérodynamique l'exigent. Ceci est possible soit quand le mat peut reposer par terre comme sur un voilier ou quand l'envergure des ailes ne nuit pas à son utilisation, comme un delta-plane. Dans la présente invention, la voilure est trapue mais conserve une grande surface efficace grâce à l'ajout de pattes arrières lui donnant une allure "chauve-souris". Cette invention permet de réduire considérablement l'envergure du mat de sorte que la voile puisse être à la verticale devant soi sans appuyer le mat au sol pour faire de la voile avec des skis aux pieds. Deux autres innovations, inhérentes à la structure particulière et à la forme de la voilure, permettent de réduire simplement la puissance de la voilure lorsque le vent augmente. Une troisième innovation, inhérente au fait que la mâture ne possède pas de point d'appui au sol, sert à soulever la voilure par vent léger et à la stabiliser dans les turbulences.

IPC: F16L37/12
Filed: 1992-04-24
Abstract: An improved plastic push in tube fitting includes a plastic body, an elastomer o-ring for sealing, and a plastic collet. The collet and o-ring are disposed in the body such that a tube can be pushed into the body through the collet and o-ring and held against withdrawal from the body by the collet. The collet is formed entirely of plastic and has a plurality of circumferential sections for encircling a tube pushed into the body. Each of the circumferential sections has a radially inwardly facing circumferential tube gripper. The tube gripper is formed by a ramp which faces a tube being pushed into the body so that the collet will encounter the ramp and move the circumferential sections radially apart. The gripper also includes a circumferential surface which faces away from a tube being pushed into the body. The circumferential ramp and the circumferential surface form a gripper edge at their junction and this edge engages and holds a tube pushed into the body through the collet. Preferably the ramp has an angle with respect to a tube pushed into the collet of between 15 and 40 degrees. Also preferably the internal angle between the circumferential ramp and the circumferential surface is between 75 and 120 degrees. The arcuate shape of the gripper edge is the same as the arcuate shape of the exterior of a tube pushed through the collet. The collet preferably is formed of hard plastics, such as poly (ether ether ketone), polyetherimide, polybutylene terephthalate, polyphthalamide and polymers of acetal homopolymer.
